Phuket, a tropical island in Thailand famous for tourism, saw a significant drop in consumption and residential spending during the COVID-19 pandemic. The number of guest arrivals was found to be the most statistically significant factor affecting consumption, especially in tourism areas, and should be considered in water demand forecasting models.
Phuket is a tropical island in Thailand that is famous for tourism. The COVID-19 pandemic resulted in the number of tourists reducing to almost zero. Since tourism contributes around one-half of the gross provincial product of Phuket, the impact was so severe that even the numbers of people employed and registered as locals decreased. Analysing the data from January 2015 to March 2021, we found that the total, residential and non-residential monthly consumptions dropped significantly after Thailand's State of Emergency was declared in March 2020. Unlike other studies that reported residential consumption increasing when people are required to stay home for a prolonged period, Phuket's residential consumption decreased by more than 10% from the pre-COVID-19 level, possibly due to the drop in peer-to-peer accommodation bookings. To study the impact on consumption in detail, we modelled using cascade regression analysis by dividing the predictors into three groups, namely socioeconomics, weather and calendar period. The results showed that the number of guest arrivals was the most statistically significant in all types of consumption and should be used as a predictor for water demand forecasting models in tourism areas.

Water Quality Audit in Drinking Water Distribution Networks

Surachai Lipiwattanakarn, Suparak Kaewsang, Chinnapan Makpiboon, Jiramate Changklom, Adichai Pornprommin

Summary: This study introduces the concept of a free residual chlorine (FRC) mass audit as a tool for water quality management in water distribution networks. By applying this concept to a real network, it is discovered that the percentage of FRC mass losses is higher than the percentage of water losses due to decay by reactions. Three performance indicators are proposed to assess FRC losses, safety, and reliability of water distribution systems in terms of water quality.

Salinity Forecasting on Raw Water for Water Supply in the Chao Phraya River

Jiramate Changklom, Phakawat Lamchuan, Adichai Pornprommin

Summary: Frequent saltwater intrusions in the Chao Phraya River have affected water supply to Bangkok and nearby areas. In this study, we proposed a method to forecast salinity at the raw water pumping station up to 120 hours in advance. We developed multiple models using linear regression and artificial neural network, and found that a multilevel model approach that considers different water levels resulted in more accurate predictions. The models were trained, selected, and tested on real data, achieving RMSE values of 0.054 g L-1 at 24-hour forecast and 0.107 g L-1 at 120-hour forecast.

Theoretical Estimation of Disinfectant Mass Balance Components in Drinking Water Distribution Systems

Kittikun Wongpeerak, Natchapol Charuwimolkul, Jiramate Changklom, Surachai Lipiwattanakarn, Adichai Pornprommin

Summary: The water quality audit concept is crucial for evaluating the loss of disinfectant mass in drinking water distribution systems. This study proposes a novel method using a simple theoretical analysis to assess the loss components (Ml, Mr, and MWL) based on the ratio of water losses (p) and the ratio of disinfectant concentrations at critical points (Cp*). The results indicate the effectiveness of these equations in auditing the loss of disinfectant mass in drinking water distribution networks.
